QuillMonkey

AI-powered userscript browser assistant for editing web pages

A browser extension that lets you edit any website with AI‑generated userscripts. Just describe what you want changed, and then watch the agent work. 〝 If I don't like something about a website, I should be able to fix it immediately. 〞 Ask for something to be changed, and see the effect right away. Achieved through a combination of AI codegen and userscripts (e.g., what TamperMonkey manages). But unlike TamperMonkey, QuillMonkey enables an AI-native user flow. With QuillMonkey, you can view, edit, and enable/disable userscripts, both AI-generated or hand-written. Or, don't look at the scripts at all, and vibe your web experience. ► Natural language No coding required (but optional). Just describe the change — "make the sidebar narrower", "remove the cookie banner", "switch to dark mode". ► Full visibility See every step the agent takes. Stop or reverse its actions. No mystery, no loss in control. ► Persistent scripts Changes are saved as userscripts and re-applied automatically. Toggle them on or off at any time. ► Version history Every edit is versioned. Roll back to any previous state with a single click — no work is ever lost. ► Screenshot analysis The AI can see the page. It analyses screenshots to understand layout, colours, and visual context before writing code. ► You control tool permissions Control which actions the AI can take automatically. Require approval before writing or updating scripts — globally or per conversation. Privacy Policy https://www.quillmonkey.com/privacy
